MACHINE FOR CUTTING TILES.

To all whom it may concern:

Be it known that I, ALBERT citizen of the United States, residing at NewYork city, Rosebank, borough of Richmond, county of Richmond, and Stateof New York, have invented certain Improvements in Machines for CuttingTiles, of which the following is a specification.

My invention relates particularly to ma- \chines for cuttinginterlocking tiles adapted for coverings for floors and like surfaces,the tiles being cut from rubber or a composition of suitable materialspenetrable by a knife, which interlocking tiles may be of any designthat fancy may dictate.

The purpose of the invention is to provide a machine of the charactermentioned that will cut tilin adapted to be arranged in closely groupeseries, or series spaced one from the other or spaced from a border, orso cut the tiles as to produce a border only of any desired type.

Another purpose of the invention is to provide a machine that ispositive in action and which is rapid in operation, and which will alsocut any shape of tile from sheet material rapidly and without waste andso that the tiles, if of an interlocking type, will perfectly jointogether.

In the drawings that serve to illustrate my invention, I have shown theimproved type of machine, but I do not confine my self to the exactconstruction illustrated, as details may be varied to suit conditions.

In the drawings-Figure 1 is a front elevation of the machine, partsbeing broken away; Fig. 2 is a side elevation of the same; Fig. 3 is apartial elevation of the plunger head, and a knife fitted thereto; Fig..41 is an end view of the knife head for the plunger; Figs. 5, 6 and 7are diagraphic views of cut tiles of the interlocking type, illustratinga compact formation, a border formation, and border and body format-ionseparated somewhat widely from each other. Fig. 8 is an enlarged detailview showing certain features of construction of the worm gearingcomprised in the means for actuat' ing' the feed rolls of the machine.

In Figs. 5, 6 and 7, I have illustrated diagraphically one form ofinterlocking tile S. JANIN, a

that can be produced by the improved machine to be hereinafterdescribed. In Fig. 5 the improved tiling is shown as closely groupedtogether, the tiles being designated as c and the sheet of tiles as G.In Fig. 6 the sheet C is shown provided with borders 0" also produced bythe improved machine, which borders are somewhat close together, and mayor may not be used, in connection with a closely grouped body portion inthe center of the design; whereas in Fig. 7 the sheet C is also shown asprovided with borders that may be used alone or in connection withclosely grouped tiling, and the said borders, which are designated as 0and 0 are shown spaced some distance apart, and the spacing between theborder or borders and the body portion of the design may be greater orlesser, as occasion may demand.

With reference to the machine shown particularly in Figs. 1 and 2, abase A, is provided of any approved formation, but the top of the saidbase is in the form of a flat table 10. On this table adjacent to theside portions of the base, standards 11, are secured and these standardsat their forward lower portions are preferably cut away as is shown inFig. 2, and at such point are connected by a brace 11*, shown in Fig. 1,and the said standards are likewise strengthened by ribs 11 A boxbearing 12, of any suitable description is mounted upon the upper end ofeach standard 11, and in these bearings, a drive shaft 13 is mounted torevolve, being provided with a crank 14, between the said bearings, asshown in Fig. 1. The upper, preferably flattened, enlarged portion of alink 15, is pivotally connected with the crank 14, and the lower end ofthe said link 15, is made to enter between box bearings 17*, located atthe upper end portion of a plunger 17 being pivotally connected with thesaid plunger by a pin 16, passed through the link and into the saidbearings 17*. The link 15, may be of any suitable formation.

A head 18, is attached to or made integral with the lower end portion ofthe plunger 17, which head may be of any suitable from the base A. Atone end of the roller shaft 22, a gear 25, of desired size is securedand the feed roller 23, is shown provided with flanges 22 at its endportions. A sec- 0nd feed roller 26, of lesser diameter than shaft 13.

the roller 23, is mounted to turn above the said roller 23, and thematerial in sheets is fed by the said rollers, onto the aforesaid table10. The roller 26, is secured to a shaft 27, mounted in boxes 28,slidable in frames 29, erected upon the upper front side portions of thebase, and set screws 30, or their equivalent, pass through the saidframes 29, and into the said boxes 28, whereby, to adjust the roller 26,toward and from the roller 23, and the said set screws 30, likewiseserve as mediums to apply tension to the upper roller 26.

At the right hand end of the upper roller shaft 27, a small gear 31, issecured, that meshes with the lower and larger gear 25, so that thespeed of the two rollers will be more or less uniform.

A vertical shaft Set, is mounted to revolve in a bearing 32, at theouter side face of one standard 11, and likewise revolves in a hearing33, located at the right hand side of the base A, as shown in Fig. 2.This shaft 34:, is provided with a bevel gear 35, at its upper end, thatmeshes with the gear 21, of the At the lower end of the said drivenshaft 34, a feed gear B, is secured in any suitable manner, and the bodyor hub portion of this feed gear, is provided with a worm 36, adapted tomesh with the teeth of the larger driving gear 25, as shown best in Fig.2. The said worm 36, at its upper end portion, is provided with aremovable section 38, that is adapted to be fitted in a groove orchannel 39, in the face of the hub or body of the feed gear B, as shownin Fig. 8. When the removable section 38, of the worm is in position itwill convey a maximum feed to the feed rollers, and when the saidsection 38, of the worm is removed, the

ear B, will impart a minimum feed to the said feed rollers 23, and 26.The removable section 38, of the worm may be held in position in anyapproved manner. As shown herein, a threaded aperture 461, is producedin the channel 39, and a corresponding aperture 11*, is produced in theaforesaid removable worm section 38, and a pin or the equivalent ispassed through the aperture 4:1 into the aperture ll.

lVhile the cutting of tiles is being effected, it is necessary that thefeed rollers 23, and 26,. should remain stationary. To that end, thebody or hub of the feed gear B, is pro vided with a tooth 40, betweenthe widest spaced portion of the worm 36. This tooth at the moment theknife reaches the sheet from which the tiles are to be cut, entersbetween the teeth of the larger gear 25, and holds said gear stationaryduring the cutting operation, the length of the tooth 10, being justsufficient to release the said gear 25, at the moment the knife hastraveled upwardly to clear the sheet of material fed thereto, andimmediately upon the release of the gear 25, from the teeth 4E0, thefeeding operation is continued.

As shown in Fig. 4, the head 18 of the plunger 17, is cut away at itssides to receive clamping strips 42, that extend below the underface ofthe said head 18, and the projecting portions of the clamping strips 42receive between them, the head 43, of a knife H, of desired pattern.Bolts 45, are utilized to secure the clamping strips 42, to the saidhead 18 of the plunger, and the head 13, of the knife.

In the operation, as long as the worm 36, is in engagement with the gear35, the feeding of the sheet material to the knife is continued, theknife being at such time in an upper position, and the feeding likewisecontinues until the knife has descended and closely approached thematerial, at which time the tooth 10, which may be termed a stop-tooth,engaging with the gear 25, prevents its rotation, and as stated suchengagement is continued while the knife is cutting through the materialand is being withdrawn therefrom. \Vhen the pattern is such as is shownfor example in Figs. 5 and 6, but a short feed is required owing to thecomparatively close spacing of the cuts 0, 0, between which the rows oftiles are produced, as indicated in said Figs. 5 and 6, and at such timethe detachable section 38, of the worm is removed, but when the spacingbetween the cuts 0", 0 is greater, as indicated in Fig. 7, a longer feedis necessary, and at such time the removable worm section 38, is securedin position on the feed gear B.

This machine is very simple, and is particularly well adapted for thepurpose intended, being applicable for cutting tiles or similar articlesof any design by changing the knives, and it is also evident that themachine can be economically constructed and that it is positive andreliable in its operation.

What I claim as new and desire to secure by Letters Patent is carried bythe table, a plunger having vertical movement in said uprights, a driveshaft for the plunger, feed rollers located in front of the said tableone above the other, the uppermost roller being of lesser diameter thanthe lowermost roller, and gears secured to the shafts of said rollers,which gears are in mesh, the upper gear being smaller than the lowerone, of a shaft driven from the actuating shaft of the plunger, a feedgear carried by the said driven shaft, a worm on said gear meshing withthe teeth of the larger roller gear, and a stop tooth also carried bythe said feed gear at a point between the diverging ends of the worm forthe purpose described, the said worm provided with a removable terminalwhereby the feed of the rollers may dered greater or less.
